JS-388
Semitransparent silicone sealant

JS-388 semi transparent silicone sealant is a single component, medium modulus, neutral curing adhesive. JS-388 semi transparent silicone sealant product can produce superior adhesion to most building materials.

Product features

1. Easy to use: can be squeezed out for use at any time;

2. Excellent thixotropy and extrudability, which can be extruded at - 5 ℃ to 40 ℃;

3. Good adhesion and excellent adhesion to most building materials;

4. Excellent weather aging resistance;

5. It is non irritating and non corrosive to metal, coated glass, mirror glass, concrete, marble, granite and other building materials, overcoming the shortcomings of acid glue (ordinary glass glue) corrosive materials.

Operation and Safety
  • JS-388 semi transparent silicone sealant is not suitable for structural assembly.
  • It is not easy to use in the following situations:
  • 1. All materials that can exude grease, plasticizers, or solvents, as well as certain unvulcanized or partially vulcanized rubbers and tapes;
  • 2. Closed areas (silicone sealant needs to be cured with moisture in the air);
  • 3. Long term immersion and year-round underground humid environment;
  • 4. The paint surface may cause sealing failure due to cracking or peeling of the paint film;
  • 5. Frosted or damp surfaces;
  • 6. Will come into direct contact with the surface of food;
  • 7. Places susceptible to mechanical wear and tear;
  • 8. Avoid contact with rubber materials (such as rubber strips, rubber pads, etc.) to avoid yellowing;
  • 9. Avoid contact with acidic or alkaline substances (such as exterior wall cleaning solution) to avoid discoloration;
  • 10. When the surface temperature of the material is below -5 ℃ or exceeds 40 ℃, construction is not suitable;
  • 11. All building materials used in engineering have successfully passed adhesion, compatibility, and contamination tests.
